Splitting method for a liquid crystal display (LCD)

A splitting method of an LCD panel having a first substrate and a second substrate, wherein the splitting method comprises the steps of:

• (A) providing an incision head and using the incision head to cut and scribe a split line in the first substrate;
• (B) providing a splitting apparatus, wherein the splitting apparatus comprises a first splitting device and a second splitting device disposed opposite to the first splitting device, and the second splitting device comprises at least one protrusion adjustment device;
• (C) splitting the first substrate at and along the split line into a split plate and a retained portion by extruding the second substrate using the at least one protrusion adjustment device to form a respective at least one extrusion in the second substrate, each extrusion extending from the second substrate and forming a protrusion in the first substrate at the split line of the first substrate, wherein the first substrate is split at and along the split line by the protrusion to separate the split plate from the retained portion, the protrusion is a portion of the first substrate that protrudes from the split line further than rest of the first substrate;
• and
• (D) removing the split plate using the first splitting device;
• wherein the first splitting device comprises a first retaining member and the second splitting device comprises a second retaining member, and
• during the step (C), the first retaining member and the second retaining member clamp the LCD panel therebetween such that forming the extrusion in the second substrate causes the extrusion to extend from the second substrate and into the first substrate to form the protrusion in the first substrate,
• wherein during step (C), a projection of the first retaining member on the first substrate does not overlap the split line;
• and
• wherein the first substrate is a color filter substrate, and the second substrate is a thin film transistor array substrate.
